MACHINE FOB IEINING 0R RECOVERING MIARL AND THE- LIKE.

Application filed October 8, 1921.

To all whom it may concern:

Be it known that we, J OSEPH F. CARNEs and JOSEPH F. HALDER, citizens of the United States, residing at Ceresco and Battle Creek, respectively, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Machines for Mining or Recovering Marl and the like, of which the following is a specification.

This invention relates to improvements in machines for mining or recovering marl and the like.

The main objects of the invention are First, to provide an improved machine for mining or removing marl from the beds of lakes or ponds, which is very efficient.

Second, to provide an improved machine of the class described which is easily manipulated to remove substantially the entire bed of marl.

Third, to provide an improved structure of the class described having these advantages which is simple and economical in structure and not likely tov get out of repair.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

The objects of the invention are accom' plished by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of the invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which: a Fig. I is a perspective view of a machine for mining marl and the like embodying the features of the invention, the scow on which the machine is usually mounted not being illustrated.

Fig. II is a detail View partially in vertical section on a line corresponding to line 22 of Fig. III.

Fig. III is a detail vertical View partially in horizontal section on a line corresponding to line 3-3 of Fig. II.

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the head or excavating member 1 of the machine is pref- Serial No. 506,431.

erably that shown and described in detail and claimed in our co-pending application, filed concurrently herewith Serial No. 506,430. This head member is provided with an impeller comprising blades 3 having cutters 2 projecting beyond the periphery of the head. ,The marl or like material is freed from the bed and mixed with water by the impeller and discharged through the conduit 4. In practice the bed member 5 is mounted upon a scow to project at the side thereof. This scow is not illustrated as it forms no part of our present invention. The scow is anchored over the bed of marl at the side thereof and the bed member 5 manipulated or the scow manipulated to suitably position the machine as the work progresses.

On the bed member 5 is a frame, designated generally by the numeral 6, carrying the laterally projecting plate-like brackets 7 the brackets being spaced horizontally. The impeller shaft 8 is slidable longitudinally through the bearing members 9 carried by these brackets. The head 1 is supported by the rods 10 which are slidable through bearings 11 disposed at the corners of the brackets 7 These bearings 11 are of considerable length and the brackets being substantially spaced the rods are rigidly supported against lateral movement. The upper ends of the rods are connected by a spider 12 which carries a bearing 13 for the impeller shaft 8.

On the upper bracket 7 is a beveled gear 14 having splined engagement or sliding engagement with the impeller shaft, the shaft being shown as square. A gear 15 on the jack shaft 16 meshes with the gear 1 1. The jack shaft is provided with a balancing wheel 17 and is driven from a suitable source of power, not illustrated, an internal combustion engine mounted upon the scow being employed in practice.

The head is raised and lowered by means of the cable 18 passed over the pulley 19. This pulley runs to a winch or other control 'means, so that the head may be raised from the bed or lowered to the work as may be desired, the weight of the head and its supporting parts being sufficient to feed it into the material.

Our improved machine for mining marl and the like is very efficient and enables the rapid and economical removal of marl and like material from beds of' lakes and ponds or from other situations where there is a plentiful supply of water, so that the water may be supplied to the machinein sufficient quantities to permit the mixing or dilution of the material and water by the impeller blades and its discharge through the con duit.

-Iaving thus described our invention, what we claim as new, and desire to secure by Letters Patent, is :v 1. In a structure ofthe class described,

the conbination of a head provided with an impeller, an impeller shaft, a bed member, a supporting frame mounted on said bed member and provided with laterally projecting horizontally spaced plate-like brackets, bearing members in which said shaft is longitudinally slidable carried by said brackets, supporting rods on which said head is mounted, said brackets being provided with slide bearings for said rods, a spider connecting the upper ends of said supporting rods, said spider carrying a bearing in which the shaft is longitudinally slidable, a beveled driven gear mounted above the upper bracket and having splined driving engagement with said shaft, a jack shaft on said frame provided with a gear meshing with said gear on'said impeller shaft, a pulley 011 said frame, and a cable connected to said head and arranged over said pulley whereby the head may be raised and lowered.
